Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of a magnetic circuit when the first sliding sleeve 7 is engaged;
fig. 3 is a schematic view of the magnetic circuit when the second sliding sleeve 8 is engaged;
fig. 4 is an enlarged view of a in fig. 3.
The specific implementation mode is as follows:
as shown in fig. 1-4, a secondary transmission coil assembly comprises an iron core shell 1 with a ring-groove structure, an annular gap 1a coaxially matched with the inner side of the iron core shell 1 on the inner side of the iron core shell, and the height of the inner side of the iron core shell 1 on the annular gap 1a is lower than that of the outer side of the iron core shell 1 through the annular gap 1 a. A coil 5 is connected to the inside of the core case 1 through an epoxy resin 5 a.
One side of the upper opening end of the iron core shell 1 is covered with a first end cover 2, and one side of the bottom surface of the iron core shell 1 is provided with a second end cover 3. And the second end cover 3 is fixedly welded with the bottom surface of the iron core shell 1. First end cover 2 and second end cover 3 be L shape structure for being annular structure and cross-section, the cell wall terminal surface looks mutual pressfitting of first end cover 2 and second end cover 3 is in the same place, and the width of the 3 tank bottoms of second end cover is greater than the width of the tank bottom of first end cover 2. And an outlet ring 5b with one end connected and matched with the coil 5 is arranged in the iron core shell 1, the first end cover 2 and the second end cover 3 in a penetrating way. An outgoing line, one end of which is connected to the coil 5, is led out of the coil assembly through an outgoing line ring 5b, and a plug-in component is connected to one end of the outgoing line. Since the outlet ring 5b, the outlet wire, and the insert assembly are common structures in electromagnetic clutches, their structures will not be described here.
The end face of the top end of the annular notch 1a is provided with a slot 1c, and the slot 1c is of an annular groove structure and is coaxially distributed with the iron core shell 1. The annular notch 1a is provided with an annular platform 1b extending outward.
The outer side of the ring platform 1b, namely the center hole of the iron core shell 1, is sequentially distributed with a first sliding sleeve 7, a second sliding sleeve 8 and a lining 4 which are coaxially distributed with the iron core shell 1, the lower end faces of the first sliding sleeve 7 and the second sliding sleeve 8 are in contact with the upper end face of the ring body 9, and the lower end face of the first sliding sleeve 7 is welded and fixed with the upper end face of the ring body 9.
The outer side of the ring body 9 is provided with a cylindrical lining 4, the lower end of the lining 4 is contacted with the groove bottom surface of the second end cover 3, and the inner ring surface of the ring body 9 is attached to the outer circle surface of the lower end part of the lining 4. And the upper end part of the bush 4 is provided with a ring of annular steps 4a which form limit fit with the first end cover 2.
A baffle ring 6 which is coaxially distributed with the iron core shell 1 is arranged between the coil 5 and the first sliding sleeve 7, an inserting ring 6b inserted into the slot 1c extends downwards from the lower end surface of the baffle ring 6, an annular limiting block 6a protrudes outwards from the outer side of the upper end part of the baffle ring 6, and the outer circular surface of the limiting block 6a is in contact with the outer circular surface of the upper end part of the first sliding sleeve 7 to form limiting fit with the first sliding sleeve.
Self-lubricating coatings of polytetrafluoroethylene are sprayed on the surfaces of the first sliding sleeve 7 and the second sliding sleeve 8 and the outer circular surface of the lining 4. The height of the second sliding sleeve 8 is less than that of the first sliding sleeve 7. The baffle ring 6, the ring body 9 and the lining 4 are all made of non-magnetic materials.
The working process is as follows:
after the coil 5 is electrified, the first sliding sleeve 7, the second sliding sleeve 8 and the iron core shell 1 are magnetized to generate magnetic force, and the first sliding sleeve 7 is attracted to the first end cover 2. Then, the first-stage transmission is carried out: the first sliding sleeve 7 can move towards the first end cover 2 direction and simultaneously can drive the ring body 9 to move towards the first end cover 2 direction because the first sliding sleeve 7 is welded and fixed with the ring body 9, and meanwhile, the second sliding sleeve 8 also moves towards the first end cover 2 direction under the driving of the ring body 9. But the ring platform 1b plays a role of limiting the ring body 9. The first sliding sleeve 7 is lifted to a certain height and then reaches the limit position, and a certain distance is kept between the top end of the first sliding sleeve 7 and the first end cover 2.
Because the height of the first sliding sleeve 7 that highly is less than of the second sliding sleeve 8, so after first sliding sleeve 7 reachs extreme position, promptly the ring body 9 drives the second sliding sleeve 8 and removes to extreme position after, the magnetic return volume will shift to 8 one sides of second sliding sleeve, thereby make the rise magnetic force increase of second sliding sleeve 8, make the strong suction that second sliding sleeve 8 and first end cover 2 formed, second sliding sleeve 8 can be under the effect of this strong suction, make second sliding sleeve 8 continue to drive bush 4 again and continue to move to 2 axial of first end cover together, accomplish secondary drive promptly. So that the gap between the top end of the second sliding sleeve 8 and the first end cover 2 is smaller than the distance between the first sliding sleeve 7 and the first end cover 2.
The two-pole thrust drives the second sliding sleeve 8 to move, and the stroke and the thrust of the bushing 4 are greatly increased.
As can be seen from the comparison of fig. 2 and 3, due to the arrangement of the notch 1a and the baffle ring 6 in fig. 2, the stroke of the magnetic circuit is increased under the blocking of the baffle ring 6 after the coil 5 is electrified, and the second sliding sleeve 8 forms two-pole transmission movement under the action of two acting forces, so that the stroke of the bushing 4 and the stroke of the coil magnetic circuit are increased, and the performance of the electromagnetic attraction of the coil assembly is improved on the premise of not increasing the diameter of the clutch. The arrows in fig. 2 and 3 are magnetic loops.
